- Abstract
Background/objective: To determine the prevalence of visual impairment (VI), uncorrected refractive errors (URE), and effective refractive error coverage among individuals aged 15-50 years in Koshi Province, Nepal., Methods: A population-based cross-sectional study was conducted in Koshi Province in which 4800 participants were selected from 80 clusters. The study teams visited the selected households and conducted eye examinations. This included monocular unaided (and aided) visual acuity assessment using a Snellen chart with tumbling E optotypes at a distance of 6 meters. Near vision was assessed binocularly using the N notation chart at a fixed distance of 40 cm for each individual. Torchlight examination and distance direct ophthalmoscopy was done. VI was defined as presenting visual acuity worse than 6/12 in the better eye. URE was defined as presenting visual acuity worse than 6/12 and improving to 6/12 or better on using a pinhole. Near Vision Impairment was defined as binocular presenting near vision worse than N8 among those age 35 years and older., Results: In total, 4057 were examined (84.5% response rate). The prevalence of VI was 3.52% (95% CI:2.89-4.13; n = 143). The prevalence of URE in the better eye was 1.95% (95% CI:1.54-2.42; n = 79). The Refractive Error Coverage and Effective Refractive Error Coverage were 34.8% and 31.3% respectively. The prevalence of NVI was 34.24% (95% CI: 32.1-36.40; n = 666)., Conclusion: The prevalence of VI and URE was low, attributed to the availability and uptake of services in Koshi province in Nepal., (© 2023.

- Abstract
Background: The COVID-19 pandemic impacted healthcare systems, including resuscitation training programs such as Helping Babies Breathe (HBB). Nepal, a country with limited healthcare resources, faces challenges in delivering effective HBB training, managing deliveries, and providing neonatal care, particularly in remote areas., Aims: This study assessed HBB skills and knowledge postpandemic through interviews with key stakeholders in Nepal. It aimed to identify strategies, adaptations, and innovations to address training gaps and scale-up HBB., Methods: A qualitative approach was used, employing semistructured interviews about HBB program effectiveness, pandemic challenges, stakeholder engagement, and suggestions for improvement., Results: The study encompassed interviews with 23 participants, including HBB trainers, birth attendants, officials, and providers. Thematic analysis employed a systematic approach by deducing themes from study aims and theory. Data underwent iterative coding and refinement to synthesize content yielding following 5 themes: (1) pandemic's impact on HBB training; (2) resource accessibility for training postpandemic; (3) reviving HBB training; (4) impacts on the neonatal workforce; and (5) elements influencing HBB training progress., Conclusion: Postpandemic, healthcare workers in Nepal encounter challenges accessing essential resources and delivering HBB training, especially in remote areas. Adequate budgeting and strong commitment from healthcare policy levels are essential to reduce neonatal mortality in the future., (Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.)

- Abstract
Background: Global neonatal mortality necessitates access to immediate newborn care interventions. In Nepal, disparities persist in the readiness and availability of newborn care services within health facilities., Objective: This study aimed to assess this status and compare facilities that had implemented an intensive newborn resuscitation capacity building and retention programme in the past five years with those that had not., Methods: Our observational cross-sectional study involved 154 health facilities across Nepal. Through on-site inspections and maternal log reviews, we evaluated the immediate newborn care readiness and availability., Results: The mean immediate newborn care intervention availability score of 52.8% (SE = 21.5) and the readiness score averaged 79.6% (SE = 12.3). Encouragingly, 96% of facilities ensured newborns were dried and wrapped for warmth, and 69.9% provided newborn resuscitation. Practices such as delayed cord clamping (42.0%), skin-to-skin contact (28.6%), and early breastfeeding (63.5%) showed room for improvement. Only 16.1% of health facilities administered Vitamin K1 prophylaxis.Domain-specific scores demonstrated a high level of facility readiness in infrastructure (97.5%), medicine, equipment, and supplies (90.6%), and staff training (90.9%), but a lower score for neonatal resuscitation aids (28.8%). Disparities in readiness and availability were evident, with rural areas and the Madhesh province reporting lower scores. Variations among health facility types revealed provincial and private hospitals outperforming local-level facilities. A positive association was observed between the LDSC/SSN mentoring programme and both the readiness and availability of immediate newborn care services., Conclusion: This study highlights the gap between healthcare facility readiness and the actual availability of immediate newborn care interventions in Nepal. Addressing disparities and barriers, particularly in rural areas and local-level facilities, is crucial for improving neonatal survival. The positive link between the LDSC/SSN programme and service availability and facility readiness emphasises the significance of targeted training and mentorship programmes in enhancing newborn care across Nepal.

- Abstract
To reduce neonatal mortality attributable to intrapartum hypoxic events, Latter-days Saint Charities (LDSC) and Safa Sunaulo Nepal (SSN) implemented a neonatal resuscitation training, scale-up, and skill retention program. This article reports on the LDSC/SSN dissemination program and newborn outcomes associated with its implementation. To evaluate the program, we used a prospective cohort design to compare outcomes of birth cohorts in 87 health facilities preimplementation and postimplementation of the facility-based training. A paired T-test was used to determine whether baseline and endline values were significantly different. Resuscitation training began with trainers from 191 facilities attending Helping Babies Breathe (HBB) training-of-trainer (ToT) courses. Thereafter, 87 facilities from five provinces received active mentoring, scale-up assistance (6389 providers trained), and skill retention support. The LDSC/SSN program was associated with decreases in the number of intrapartum stillbirths in all provinces except Bagmati. Neonatal deaths within 24 hours of birth decreased significantly in Lumbini, Madhesh, and Karnali provinces. Morbidity associations, as defined by sick newborn transfers, decreased significantly in Lumbini, Gandaki, and Madhesh provinces. The LDSC/SSN model of neonatal resuscitation training, scale-up, and skill retention has the potential to significantly improve perinatal outcomes. It could potentially guide future programs in Nepal and other resource-limited settings.

- Abstract
Objective: Data collected from various institutions around the country was analyzed to assess the current status of cardiovascular and thoracic surgery in the country., Methods: We collected data from institutions performing cardiovascular and thoracic surgery from all over the country through direct correspondence for the year 2019. Individual institution data on the number of surgeries performed for cardiac, vascular, and thoracic surgery and its outcome in terms of mortality were compiled. The data were further evaluated depending on the type of procedures performed., Results: Overall, a total of 2264 cardiac surgeries were performed in the country in the year 2019. The majority of the surgeries were for valvular heart surgery accounting for 34.3%, followed by congenital surgeries (32.8%) and surgeries for coronary artery disease (25.9%). A total of 649 thoracic surgeries were documented, which is probably marginally less than the actual numbers because we were unable to include an additional few institutions performing low-volume or isolated thoracic procedures in this report. A total of 852 vascular procedures were performed in the country, which is probably underreported. The mortality rates for complex congenital procedures were higher than those reported in the literature and that of adult procedures such as valvular heart disease and coronary artery disease similar to literature., Conclusion: We evaluated the recent status of cardiovascular and thoracic surgery in the country with respect to the type of procedures and the postoperative outcomes.

- Abstract
Background: Intrapartum events leading to asphyxia at birth are a leading cause of neonatal morbidity and mortality in Nepal. In response, the Nepal Ministry of Health and Population adopted the Helping Babies Breathe (HBB) training curriculum in 2015 as a tool to improve neonatal resuscitation and outcomes. Although the effectiveness of HBB training has been well documented, challenges remain in maintaining skills over time. Safa Sunaulo Nepal (SSN) designed an evidence-based intervention for scaling up newborn resuscitation training and skill retention. We report on its implementation and the changes in newborn outcomes during the program period., Methods: The program empowered facility-based trainers in newborn resuscitation and skill retention at 12 facilities in Gandaki Province. Seven of 14 level I hospitals and 5 of 6 level II hospitals were selected. A single external mentor coached the facility-based trainers, provided general support, and monitored progress. Program evaluation tracked changes in newborn metrics over 21 Nepali months (March 2018-November 2019). All deliveries occurring in the health facilities during the program period were included in the evaluation. We assessed program effectiveness by analyzing time trends of neonatal mortality, morbidity, and stillbirths., Results: We gathered data on neonatal health outcomes of 33,417 deliveries, including 23,820 vaginal deliveries and 9,597 cesarean deliveries. During the program, 43 facility-based trainers taught resuscitation skills to 425 medical personnel and supported skill retention. Neonatal deaths within 24 hours of birth (incidence rate ratio [IRR]=0.993, P =.044) and newborn morbidities (IRR=0.996, P <.001) showed a significantly declining trend., Conclusion: Our findings suggest that the SSN program had a substantial influence on critical neonatal outcomes. Future neonatal resuscitation capacity-building and skill retention efforts may benefit from incorporating elements of the program., (© Clark et al.)

- Abstract
Most pathology of the thymus gland warrant its surgical removal; and this requires significant expertise and adequate medical set-up. This study aimed to audit the results of thymectomies performed in a specialised tertiary level centre in a resource-poor country. The outcomes of open and minimally invasive video-assisted thoracoscopic surgery (VATS) thymectomies were also compared. Out of 58 patients operated at Department of Thoracic Surgery, Manmohan Cardiothoracic Vascular and Transplant Center, Maharajgunj, Kathmandu, Nepal between October 2012 and January 2019, 33 patients underwent open thymectomy and 25 had VATS thymectomy. We conducted a retrospective search to look at operative time, blood loss and length of postoperative hospitalisation. The open surgery group was followed for an average of 32 months, and the VATS cohort for 38 months. No significant differences were found in mean operative times and overall survival between groups. In selected cases, thymectomy via VATS is safer and comparable to open thymectomy in terms of operative safety and oncological completeness. Key Words: Thymus, VATS, Thymectomy, Outcome.

Introduction: Head and neck cancer is the sixth most common cancer in the world. The disease burden is increasing at an alarming rate in developing Southeast Asian countries. This study aims to report the histopathological spectrum of oral cavity lesions at a tertiary cancer center in central Nepal., Methods: This study included all those cases of oral cavity lesions, of which diagnostic biopsy was done from January 2018 to December 2019. The data were retrieved from the Department of Pathology of BP Koirala Memorial Cancer Hospital. The study proposal was approved by the Institutional Review Committee at BPKMCH (Ref: 247/2020) on 28th June 2020. Convenience sampling was done. Data was analyzed using Statistical Package for the Social Sciences version 20 using descriptive statistics., Results: A total of 851 cases of oral cavity lesions were included in this study. The mean age of the study population was 55.9 years, with male to female ratio of 3:1. Malignant lesions composed of 472 (55.5%) cases followed by premalignant lesion of 104 (12%). More than 453 (95%) malignant cases were squamous cell carcinoma, of which 342 (75%) were a well-differentiated type. The buccal cavity is the most common site of malignant lesion 212 (45%), followed by tongue 96 (20%) and lower gingivobuccal region 86 (18%)., Conclusions: Malignant lesions are the most common histopathological findings in the oral cavity lesion with squamous cell carcinoma type. Oral cancer is common cancer that can be prevented and cured if detected early.

- Abstract
Background: Undernutrition is highly prevalent in Nepal, which interferes with physical and mental development among children. It is one of the severe health problems contributing to the significant portion of the disease burden. This study aimed to explore socio-demographic and healthcare-seeking related predictors of undernutrition among children under five years old in Dang, Nepal., Methods: This was a descriptive cross-sectional study. A sample of 426 children was participated through stratified proportionate random sampling to identify socio-demographics and healthcare-seeking predictors of undernutrition. Multivariable regression was applied to identify the independent predictors of undernutrition., Results: This study found that children below 24 months of age were more likely to be undernourished than children aged 24-36 months. Female children (OR=2.32, 95% CI: 1.19-4.54), illiterate or non-formally educated women (OR=4.09, 95% CI: 1.84-9.08), mother's occupation other than a housewife (OR=13.05, 95% CI: 4.19-40.68), labor work of father (OR=2.40, 95% CI: 1.04-5.57) had increased risk of undernutrition among children. Similarly, food insufficiency from their land, antenatal care visit, postnatal care visit, and delivery place were significantly associated with childhood undernutrition among children. Conclusions: The study showed that undernutrition among children is associated with age and gender of children, educational attainment of the mother, food sufficiency, health-seeking practices of the mother during pregnancy, delivery, and postnatal. Socio-demographics and health-seeking practices related predictors must be explicitly considered to address undernutrition among children under the age of five years.

- Abstract
Background: The World Health Organization recommends initiation of breastfeeding within 1 hour of birth and exclusive breastfeeding up to 6 months of age. Infant feeding practices, including suboptimal breastfeeding practices, are associated with stunting. Rate of stunting was highest in the Mid-western region and lowest in the Eastern region of Nepal. This study aimed to assess the breastfeeding practices in these two regions, as well as to identify factors associated with partial breastfeeding., Methods: We conducted a health facility-based cross-sectional study in the Mid-western and Eastern regions of Nepal from December 2017 to May 2018. Investigators administered a pre-tested questionnaire among consecutive 574 mother-infant dyads at different levels of health facilities. We dichotomized the breastfeeding pattern to partial breastfeeding and full (exclusive or predominant) breastfeeding. We conducted multivariable logistic regression to identify factors associated with partial breastfeeding within 6 months of age., Results: There were 574 infants included in the study, all of which received at least some breastfeeding. Only 23.2% of infants were exclusively breastfed until 6 months, with 28.2% predominantly breastfed and 48.6% partially breastfed. Partial breastfeeding rate was 52.3% in the Mid-western region and 44.4% in the Eastern region. Breastfeeding was initiated within an hour from birth in 67.2% of infants. One-quarter of infants were given pre-lacteal feed, honey being the commonest. Knowledge of the recommended duration of exclusive breastfeeding was inadequate in 16, and 65% of mothers reported breastfeeding problems in the first 6 months. Firstborn and low birth weight infants had a significantly higher rate of partial breastfeeding. Partial breastfeeding was also higher when infants were not breastfed within 1 hour from birth, mothers reported having breastfeeding-related problems or had inadequate knowledge of the duration of exclusive breastfeeding., Conclusion: Nearly half of the infants were fully breastfed at 6 months of age in Nepal. The rate of partial breastfeeding was higher with inadequate knowledge on duration of exclusive breastfeeding or late initiation of breastfeeding or perceived breastfeeding problems. Hence, programs should address knowledge and practice gaps in breastfeeding practices, particularly among mothers of low birth weight and firstborn infants.

- Abstract
Background: This study was conducted to identify knowledge, attitude and practice of the public in relation to eye health and to assess their knowledge of eye health seeking behaviour., Methods: A three-stage cluster survey was conducted in 15 selected districts of the five development regions of Nepal from May to December 2017.One hundred clusters and fifty households from each cluster were randomly selected. A semi-structured questionnaire was developed in English and translated into Nepali and back translated by experts. Data were entered in CSPro 5.0.3 software and imported to R 3.4.1 software for analysis., Results: Three fourth of respondents were between the age of 20-59 years (84 %) and one third were female (37.4%). 78% of respondents had basic knowledge about ocular diseases (ranging from 68 to 95%). No single method was found to be more appropriate than the other to provide eye health education to the people living in different geographical locations. Radio was more appropriate to provide health education in Doti and television in Saptari district. Around 2% of the people still depended on drug retailers, 0.6% on self-medication and 0.1% on traditional healers for treatment., Conclusions: The knowledge, attitude and practice of the respondents varied between various districts and with different demographic characteristics. The overall knowledge, attitude and practice score and respondent's knowledge about common eye diseases requires improvement. Different methods can be used to educate public about eye health and common eye diseases.

Hippocratic oath, written 4th or 5th century BC, is still the binding mantra for physicians, which swears to fulfill to the best of one's ability and judgement, and treat sick human beings not just illness. But with changing health trends in southeast Asia region, there is a dramatic shift in patients and patients' party expectations regarding treatment, recovery, complications, and death. Such expectations havelead to violence against physicians and shift towards alternative medical practice. This article explores the possible rise of defensive medicine and its broader implications in health care system in Nepal with regard to the new 'Muluki Aparadh Samhita Ain 2074/Criminal (Code) Act 2017'.

- Abstract
Background: Acute iodine excess in newborns can cause hypothyroidism, but there are limited data on the effects of iodine excess on thyroid function in older infants. The aim of this study was to measure the effects of chronic excess iodine intake on thyroid function in 6-24-month-old infants., Methods: In this cross-sectional study, infants (n=696) in eastern Nepal were studied. Spot urine samples, venous blood samples, and household salt samples were collected, and urinary iodine concentration (UIC), serum free thyroxine (fT4), thyrotropin (TSH), thyroglobulin (Tg), and titrated household salt iodine concentration (SIC) were measured. Daily iodine intake was calculated from UIC based on estimates of urine volume at this age., Results: Median (25th-75th percentile) household SIC was 89 (70-149) ppm, while national legislation stipulates a fortification level of 50 ppm. Median UIC was 407 (312-491) μg/L; 76% of infants had a UIC >300 μg/L, suggesting iodine excess. Calculated mean iodine intake in 12-24-month-old infants was 220 μg/day, exceeding the recommended safe upper limit for iodine at this age (200 μg/day). Among the infants, 15.8% had an elevated Tg, 7.4% had subclinical hypothyroidism, but <1% had overt hypothyroidism. UIC was not a significant predictor of thyroid function, thyroid hormones, or Tg., Conclusion: In 6-24-month-old infants exposed to excessive iodine intake, ∼7% have subclinical hypothyroidism but <1% have overt hypothyroidism. These findings suggest the thyroid in late infancy is already able to adapt to high iodine intakes and, in most cases, maintain euthyroidism.

- Abstract
Background: In the summer of 2002, a total of 5963 cases of typhoid fever were recorded in Bharatpur, Nepal (population, 92,214) during a 7-week period. A team from the Armed Forces Research Institute of Medical Sciences in Bangkok, Thailand, and the CIWEC Travel Medicine Clinic (Kathmandu, Nepal) assisted the Nepal National Public Health Laboratory (Kathmandu, Nepal) in the further investigation of this large, explosive febrile disease outbreak., Methods: Investigators conducted a thorough epidemiologic and laboratory investigation to assess the size and scope of the outbreak. In addition to subculturing of previously collected samples, blood samples were obtained from 100 febrile patients, and culture and susceptibility testing were done by standard laboratory methods. Pulsed field gel electrophoresis (PFGE) and plasmid analysis were done., Results: The majority of the isolates, including 1 from the municipal water supply, were multidrug resistant. The minimum inhibitory concentrations (MICs) of ciprofloxacin ranged from 0.19 microg/mL to 0.125 microg/mL. With use of PFGE, all isolates, including isolates from the water supply, showed an analytical similarity of 96%-100%. Multidrug-resistant isolates had a plasmid encoding for resistance, and those with resistance to nalidixic acid had a single-point mutation., Conclusions: To the best of our knowledge, this outbreak is the largest single-point source outbreak of multidrug-resistant typhoid fever yet reported, and it was molecularly traced to the city's single municipal water supply. Isolates were uniformly resistant to nalidixic acid, there was a decrease in their susceptibility as measured by MIC of fluoroquinolones, and 90% of isolates obtained were resistant to >1 antibiotic.
